Today, the use of agricultural waste is very important for the production of agricultural products, the use of biochar as a soil conditioner reduces the need for chemical fertilizers and helps maintain and access moisture for the plant, improving the growth and quality of horticultural products. To investigate the effect of biochar in the planting bed of capsicum (Capsicum annuum L.), an experiment was carried out as a completely randomized statistical design in 3 repetitions in 1401 in a commercial greenhouse located in Garmsar city. The treatments included wheat stubble biochar in proportions of zero, 10, 20, 40 and 60 g kg-1 soil. The results showed that the treatments had a significant effect on the assessed traits, so that the highest fresh and dry weight of the fruit (12.56-57.43 g), cell membrane stability index (85.39%), fruit length (12.56 cm), the number of fruits per plant (29.50), titratable acidity (1.13%), vitamin C (102.61 mg 100 g-1 FW), anthocyanin (9.94 mg g-1 FW) and the activity of enzymes Peroxidase, catalase and superoxide dismutase (4.25- 5.98- 4.25 U enzyme g-1 FW) in biochar treatment of 40 g kg-1 soil and the highest amount of dissolved solids (4.95 degrees Brix), pH (4.98) and total chlorophyll content (4.43 mg g-1 FW) was obtained in the biochar treatment of 60 g kg-1 soil, while it was the lowest in all evaluated attributes of the control. According to the obtained results, it is recommended to use biochar at the rate of 40 g kg-1 soil to improve the morphological and biochemical characteristics of Capsicum annuum L.
